Tank Emptying - Nilfisk ecoflex BR 652 Manuel D'utilisation

ENGLISH
Working with brush/pad-holder extra pressure function turned on (only for BR 652 / BR 752)
1. If the fl oor proves to be particularly diffi cult to clean, it is possible to turn on the brush/pad-holder extra pressure function by
pressing the switch (65).
2. To return to normal pressure, press the switch (65) again.
The switch (65) is enabled only when the deck (10) is lowered and the LED (68) of the switch (67) is on.
CAUTION!
In case of brush/pad-holder motor overload, due to foreign bodies which prevent them from turning, or to
excessively aggressive fl oors/brushes, the safety system stops the brushes/pad-holders after about one minute
of continuous overload.
The overload is shown by the three battery warning lights (62) fl ashing simultaneously.
If the overload takes place when the extra pressure function is on, the system automatically reduces the
pressure on the brushes/pad-holders, thus turning the extra pressure function off. If the overload persists, the
brushes/pad-holders stop.
To start scrubbing again after a brush/pad-holder stop due to overload, stop the machine by turning the ignition
key (58) to "0". Turn on the machine by turning the ignition key (58) to "I".
Battery discharge during operation
1. Until the green warning light (62) stays on, the batteries allow the machine to work normally.
When the green warning light turns off and fi rst the yellow warning light then the red warning light turn on, the batteries must
be charged.
• When the yellow warning light turns on the machine residual autonomy will last for a few minutes (depending on the
characteristics of the battery).
• When the red warning light turns on the machine autonomy is over: after a few seconds the brushes/pad-holders are
automatically stopped and the deck is automatically lifted. Only vacuum and drive systems still operate, just to dry the wet
fl oor and move the machine to the appointed charging area.
CAUTION!
Do not use the machine with discharged batteries, to avoid damaging the batteries and reducing the battery life.
NOTE
In case the machine drive system cannot be used in order to move the machine, see Pushing/Towing The Machine
paragraph.

TANK EMPTYING

An automatic fl oat shut-off system (27) turns off the vacuum system when the recovery tank (19) is full.
The vacuum system deactivation is signalled by a sudden increase in the vacuum system motor noise frequency, and the fl oor is
not dried.
CAUTION!
If the vacuum system turns off accidentally (for example, when the fl oat is activated because of a sudden
machine movement), to resume the operation: turn off the vacuum system by pressing the switch (63), then
open the cover (20) and check that the fl oat inside the grid (27) has gone down to the water level. Then close the
cover (20) and turn on the vacuum system by pressing the switch (63).
When the recovery tank (19) is full, empty it according to the following procedure.
Recovery tank emptying
1. Stop the machine by releasing the pedal (4).
2. Lift the brush/pad-holder deck and the squeegee by pressing the switch (67).
3. Drive the machine to the appointed disposal area.
4. Empty the recovery tank with the hose (24).
5. Remove the container with debris collection grid (26), empty it and clean it with clean water. Then install it on the suction hose
in the tank.
6. Then, rinse the tank with clean water.
